SS Block Search Configuration for Faster NR Signal Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The efficiency of searching for synchronization signal blocks (SS blocks) in user equipment is low due to the large frequency bands of New Radio (NR), requiring full-band searches, which increases time and power consumption.
Innovation Solution
Providing detection configuration information, such as frequency and location details, to user equipment to assist in targeting specific SS blocks, reducing blind detection time and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user equipment performs full-band search to determine working carrier and search for SS block, then comprehensive signal detection is achieved, but searching efficiency is reduced
Solution Approach 1:
The network device performs preliminary action by pre-configuring detection configuration information including frequency location, time location, and bandwidth of SS blocks. This allows user equipment to skip full-band search and directly search at predetermined locations, resolving the contradiction between comprehensive detection and search efficiency
Solution Approach 2:
Detection configuration information acts as an intermediary between the network device and user equipment. It carries pre-calculated search parameters that guide the user equipment to the correct SS block locations without requiring exhaustive full-band scanning, thus maintaining reliability while improving efficiency
2Reliability
If user equipment performs full-band search for SS block, then all possible signals are detected, but time consumption increases
Solution Approach 1:
The network device performs preliminary action by pre-configuring detection configuration information including frequency location, time location, and bandwidth of SS blocks. This allows user equipment to skip full-band search and directly search at predetermined locations, resolving the contradiction between comprehensive detection and search efficiency
Solution Approach 2:
The search space is segmented from a full-band exhaustive search into specific frequency locations, time locations, and bandwidth ranges provided in the detection configuration information. This segmentation reduces the search space from the entire band to predetermined locations, significantly reducing blind detection time while maintaining detection completeness
